“Key Operator” means users who, for example, have advanced skill ratherthan “Ordinary User”, that is, users who know advanced functions of thecopier 300.

“Administrator” means users who, for example, can handle maintenancetasks such as toner replenishing.

“Purchaser” means users who, for example, are in charge of purchasingsupplies for the copier 300 (for example, toner units, paper, and thelike for replenishment), but their operation skill is the same as thatof the “Ordinary User”.

The user attribution is arbitrary information registered user by user.

The program memory unit 13 may be a semiconductor memory device whichstores programs to be executed by the control unit 10. In thisembodiment, the program memory unit 13 stores a program for realizing asystem for dynamic contents such as CGI (Common Gateway Interface) andthe like. Hereinafter, such the program for CGI will be referred to as“CGI program”. According to the CGI program, the control unit 10executes other application programs and/or accesses databases todynamically generate web page data. Thus generated web page data may bewritten in, for example, HTML (Hyper Text Markup Language) which issuitable for data transfer via the Internet 3.

The manual database 14 may be a rewritable storage unit such as a harddisk drive which stores electronic manual files written in, for example,HTML. The electronic manual files represent manuals for the productsdealt by the manufacturer of the copier 300. FIG. 4 is a diagram forexplaining an example of the electronic manual files being stored in themanual database 14. As shown in FIG. 4, records prepared for the modelsare stored in the manual database 14. That is, the electronic manualfiles in one record represents a series of manual for the correspondingmodel, and those files are categorized in accordance with the functionof the model. Some of the electronic manual files will be selected inaccordance with, for example, the user's request, thus manual pages willbe created case by case.

The input unit 15 comprises, may be a keyboard, a mouse, and the like,to be used for inputting (editing) data to be stored (being stored) inthe customer information database 12 and the manual database 14. Forexample, the input unit 15 is used for entering new customer informationto the customer information database 12, or for adding or updating theelectronic manual files in the manual database 14.

A process for providing electronic manuals according to the electronicmanual providing system 1000 according to the present embodiment willnow be explained below with reference to the flowchart shown in FIG. 5.

In this embodiment, a web site is established by the businessmanufacturing/vending the copier 300 to present various information(corporate information, product information, recruit information, andthe like) through the Internet 3. The web site is built in the center100. The web site includes pages for presenting electronic manuals(hereinafter referred to as “manual pages”) available by using theterminal 500 through the Internet 3.

When a user operates the terminal 500 and accesses the web site (stepS101: YES), the control unit 10 executes the CGI program and the like inthe program memory unit 13 to generate web page data of a top page ofthe web site as shown in FIG. 6. The control unit 10 controls the CCU 11to transmit the web page data to the terminal 500 (step S102). Thecontrol unit 10 also generates information for distinguishing theterminal 500 (such as cookie) and transmits it to the terminal 500 inorder to identify the terminal 500 during the following sessions.Accordingly, “terminal 500” in the following explanations indicates theterminal 500 that accesses the center 100 at step S101.

As shown in FIG. 6, the top page includes some hyperlinks to the otherpages in the web site. The web site includes unlimited pages being opento the public and limited pages which limits the users to registeredcustomers (hereinafter, referred to as “customer page”). The registeredcustomer means genuine users of the copier 300.

Since the customer page is limited to the registered customers, visitorsother than the registered customers (hereinafter, the registeredcustomer will be referred to as “customer”, and the visitors other thanthe registered customers will be referred to as “visitor”) may notselect the hyperlink for the customer page. In this case (step S103:YES), the center 100 continuously provides the top page (unless anyhyperlink is selected). The top page also includes the hyperlink topages representing manuals (hereinafter referred to as “manual pages”).The visitors may select hyperlink to the manual pages if necessary.

If the hyperlink to the manual pages is selected (step S104: YES), anoperation for providing the manual pages for visitors (hereinafter,referred to as “visitor's manual page”) is executed in step S200. On theother hand, if the hyperlink to the manual pages is not selected (stepS104: NO), that is, the hyperlinks are not selected or the hyperlink toother page is selected, the center 100 provides the top pagecontinuously or pages corresponding to the selected hyperlink (stepS150).

The operation for providing the visitor's manual page (step S200) willnow be explained below with reference to a flowchart shown in FIG. 7.

Upon selection of the hyperlink at step S104, the control unit 10executes the CGI program and the like to generate web page datarepresenting a page for selecting a product desired by the visitor(hereinafter, referred to as “item selector page”) as shown in FIG. 8.And the control unit 10 controls the CCU 11 to transmit the generatedweb page data to the terminal 500 (step S201).

The item selector page has arbitrary selector(s) such as a combo box asshown in FIG. 8. In this case, the visitor select desired product fromthe list. More precisely, each product name in the list includesinvisible information specifying the that product (hereinafter, referredto as “item identifier”). When the user selects desired item name, thecorresponding item identifier is transmitted to the center 100.

When the CCU 11 of the center 100 receives the item identifier from theterminal 500 via the Internet 3 (step S202: YES), the control unit 10retrieves electronic manual files from the manual database 14. In thiscase, the control unit 10 obtains the manual file from the recordcorresponding to the product specified by the received item identifier.Then, the control unit 10 executes the CGI program and the like togenerate web page data representing manual page as shown in FIG. 9 (stepS204). In this case, the control unit 10 generates the web page data, sothat the page includes information represented by the retrieved manualfile. The control unit 10 controls the CCU 11 to transmit the generatedweb page data to the terminal 500 via the Internet 3 (step S205), andterminates the operation.

Another operation for a case where the customer accesses the web sitewill now be explained.

When the customer operates the terminal 500 and selects the hyperlink tothe customer page, the terminal 500 transmits a request signal forrequesting the customer page to the center 100.

When the CCU 11 of the center 100 receives the request signal from theterminal 500 (step S103: NO (FIG. 5)), the control unit 10 executes theCGI program and the like in the program memory unit 13 to generate webpage data representing a form page for inputting user ID as shown inFIG. 10. Then the control unit 10 controls the CCU 11 to transmit thegenerated web page data to the terminal 500, thus requesting thecustomer to input his/her user ID (step S105).

As shown in FIG. 10, the form page includes text boxes for inputting thecustomer's mail address, password, and corporate ID (that is, user ID),and buttons for sending or canceling the input information.

When the customer inputs his/her user ID and select the “send” button,the terminal 500 transmits the input user ID to the center 100 via theInternet 3.

When the CCU 11 of the center 100 receives the user ID from the terminal500, the control unit 10 determines whether the user is the registeredcustomer or not (step S106). In this case, the control unit 10 accessesthe customer information database 12 to determine whether user ID whichcoincides with the received ID has been registered in the customerinformation database 12 or not.

In a case where the customer information database 12 does not have theuser ID coinciding with the received user ID, or any one of the items inthe received user ID is incorrect, the control unit 10 determines thatthe user concerned is not the registered customer (step S106: NO), andterminates the process.

In contrast, in a case where the user authentication is successful, thatis, the control unit 10 determines that the user concerned is theregistered customer (step S106: YES), the control unit 10 executes theCGI program and the like to generate web page data representing acustomer page as shown in FIG. 11. The control unit 10 controls the CCU11 to transmit the web page data to the terminal 500 (step S107). Notethat the customer page includes specialized information for theregistered customers, such as support information and upgradeinformation.

As shown in FIG. 11, the customer page also includes a hyperlink tomanual pages specialized for the customers (hereinafter, referred to as“customer's manual page”). URL (Uniform Resource Locator) indicating themanual page for the customers is invisibly assigned to the hyperlink.That is, if the user selects the hyperlink with operating the terminal500, the terminal 500 transmits the URL to the center 100.

When the CCU 11 of the center 100 receives the URL indicating thecustomer's manual page from the terminal 500 (step S108: YES), anoperation for providing the customer's manual pages is carried out atstep S300.

On the other hand, in a case where the hyperlink to the customer'smanual page is not selected by the terminal 500, that is, no hyperlinkis selected or the hyperlink to another page is selected, the controlunit 10 transmits the customer page continuously or other designatedpage (step S150).

The operation for providing the customer's manual page (step S300) willnow be explained with reference to a flowchart shown in FIG. 12.

The control unit 10 accesses the customer information database 12 torefer to “Current Model” in the customer information corresponding tothe user ID received at step S106 (step S301).

Then, the control unit 10 executes the CGI program and the like togenerate web page data representing a top page of the customer's manualpages as shown in FIG. 13. The control unit 10 controls the CCU 11 totransmit the generated web page data to the terminal 500 (step S302).

As shown in FIG. 13, the top page indicates model No. (or model name)based on “Current Model” referred at step 301 The top page also includes“YES” and “NO” buttons for selecting manuals for the indicated model(“YES”) or manuals for other model (“NO”).

In case of requesting the manuals for the current model, the useroperates the terminal 500 to select “YES” button, and the terminal 500transmits a request signal for requesting manual pages of the currentmodel to the center 100 via the Internet 3. When the CCU 11 in thecenter 100 receives the request signal from the terminal 500, thecontrol unit 10 accesses the manual database 14 to retrieve theelectronic manual files for the product corresponding to “Current Model”referred at step S301 (step S304).

Upon retrieval of the electronic manual files, the control unit 10carries out a personalizing operation (step S400). This personalizingoperation will now be explained below with reference to a flowchartshown in FIG. 14.

The control unit 10 accesses the customer information database 12 torefer to the customer information (see FIG. 3) of the customer (stepS401).

If the control unit 10 finds any information in “History” of thecustomer information (step S402: YES), the control unit 10 obtainsinformation representing the date of upgrade. And, the control unit 10determines whether the number of days after the date of upgrade iswithin a predetermined period (for example, 1 month) or not (step S403).If it is determined that the number of days is within the predeterminedperiod (step S403: YES), the control unit 10 executes the CGI programand the like to generate web page data representing an option selectorpage as shown in FIG. 15. The control unit 10 controls the CCU 11 totransmit the generated web page data to the terminal 500 (step S404).

As shown in FIG. 15, the option selector page presents option between afull version of the manual for the current model (hereinafter, referredto as “full manual”) and an extract version comprising the electronicmanual files describing functions of the current model which aredifferent from the former model (hereinafter, referred to as“differential manual”). And the option selector includes “YES” and “NO”buttons for selecting the option. According to the message on the optionselector page, the user may select “YES” button if he/she requires thefull manual, or may select “NO” button if he/she requires thedifferential manual.

According to steps S402 and S403, option for the differential manual isprepared if it has been within a predetermined period since the userupgraded the copier 300. This is because it is supposed that the usermay be unfamiliar with functions of the new model around the initialstage immediately after the upgrade (in this embodiment, for 1 month),while he/she may be familiar with the functions which are the same asthose of the former model.

If the user operates the terminal 500 to select the differential manual(step S405: YES), the terminal 500 transmits a request signal forrequesting the differential manual (hereinafter, referred to as “requestfor differential”).

When the CCU 11 of the center 100 receives the request for differentialfrom the terminal 500 (step S405: YES), the control unit 10 selects theelectronic manual files describing the functions of the current modelwhich are different from those of the former model, from the electronicfiles retrieved in step S304 (FIG. 12) (step S406).

This manual file selection will now be described in detail. The manualdatabase 14 stores “Manual-File-Finder” tables (hereinafter, referred toas “MFF tables”) as shown in FIG. 16. The MFF tables are preparedcategory by category, such as copier, printer, and facsimile. As shownin FIG. 16, each table defines file name of the electronic manual filebased on model name and functions.

An example of file determination where the current model (determined atstep S301) is Model A002 and the former model (determined at step S402)is Model A001 will now be described.

The control unit 10 accesses the manual database 14 to refer to the MFFtable for the copier. And, the control unit 10 compares items for ModelA001 with those for Model A002.

In FIG. 16, as for the function “Centering”, both A001 and A002designate the electronic manual file “manu/copy/cent/001.htm”. Thismeans that there is no operational and/or functional difference betweenA001 and A002.

On the contrary, as for the function “Duplex Copy”, A001 designates theelectronic manual file “manu/copy/dup/001.htm”, while A002 designates“manu/copy/dup/002.htm”. This means that there are operational and/orfunctional differences between A001 and A002.

As comparing file names between target models, the control unit 10 picksup the file names designated by any one of the target models, andobtains the electronic file in accordance with the picked up file nameas files for the differential manual.

After thus selecting the files for the differential manual at step S406,or if the control unit 10 determined that there is no information in“History” (step S402: NO), or if the control unit 10 determined that thepredetermined period has passed (step S403: NO), the control unit 10further determines whether there is any information in “User Attribute”of the customer information concerned.

If the “User Attribute” includes any information (step S407: YES), thecontrol unit 10 selects the manual files corresponding to the userattribute information from the manual files obtained at step S304 orS406 (step S408).

The relationship between the user attribute and electronic manual files,for selecting the electronic manual files will now be described indetail. The electronic manual files are categorized, for example, byskill levels. The categories may be, for example, “Beginner”, “Basic”,“Middle”, and “Advanced”, and those categories are associated with theuser attribute, “Ordinary User”, “Key Operator”, “Administrator”, and“Purchaser”. For example, in case of “Ordinary User”, the electronicmanual files corresponding to “Beginner” and “Basic” may be selected. Inthe same manner, “Administrator” relates to “Basic” and “Middle”,“Purchaser” relates to “Beginner” and “Basic”, and “Key Operator”relates to “Middle” and “Advanced”.

If it is determined that the user attribute is not registered (stepS407: NO), the control unit 10 determines the electronic manual filesselected at step S304 or S406 to be presented.

The process flow forwards to step S305 (FIG. 12). In step S305, thecontrol unit 10 executes the CGI program and the like to generate webpage data representing an electronic manual page indicative of theselected electronic manual files. The control unit 10 controls the CCU11 to transmit the generated web page data to the terminal 500.

FIGS. 17, 18A, and 18B are diagrams showing an example of examples ofelectronic manual pages generated at step S305.

As shown in FIG. 17, the electronic manual page has two sections,section A and section B (indicated by broken lines). The section Aincludes ordinary objects such as menu buttons for selecting items ofthe manual. Those menu buttons are prepared for manual search. Thesection B includes contents of the electronic manual files selected atstep S406 or S408. It is featured that the section B may occupies thepage, that is, the electronic manual page shows the contents of theselected electronic files so as to focus the user on it.

The menu buttons in the section A may represent, for example, “TroubleShooting”, “How to Use”, “Functions”, “Recommended Functions”, and thelike. When the user selects the menu button “Trouble Shooting”, troubleshooting information corresponding to the user's “Current Model” will bedisplayed in the section B as shown in FIG. 18A.

The trouble shooting information may be in hierarchical structure, thatis, trouble index information representing kinds of troubles links totext and/or image files representing solutions. In response to theselection of the trouble index (by clicking or the like), the solutioninformation is presented step by step. The solution steps may berepresented by, for example, comprehensive movie or animation.

In a case where the menu button “Recommended Functions” is selected,information representing tips or the like recommended by themanufacturer/vendor of the copier 300 will be displayed in the sectionB.

A case where the user desires the electronic manual for a model otherthan the user's current model will now be described. When “NO” button onthe top page of the user's manual pages is selected, the terminal 500transmits a request signal for requesting manual for other model to thecenter 100.

When the CCU 11 of the center 10 receives the request signal from theterminal 500 (step S303: NO), the control unit 10 executes the CGIprogram and the like in the program memory unit 13 to generate web pagedata representing the item selector page as shown in FIG. 8. The controlunit 10 controls the CCU 11 to transmit the data to the terminal 500(step S306 (FIG. 19)).

As aforementioned, the item selector page has selector(s) such as acombo box or the like for selecting a product (model). In response tothe selection of the product, the terminal 500 transmits informationspecifying the selected product (product specifying information) to thecenter 100 via the Internet 3.

When the CCU 11 of the center 100 receives the product specifyinginformation from the terminal 500 (step S307: YES), the control unit 10accesses the manual database 14 to retrieve electronic manual filescorresponding to the product (hereinafter referred to as a “targetproduct”) specified by the received product specifying information (stepS308).

The control unit 10 executes the CGI program and the like in the programmemory unit 13 to generate web page data representing an electronicmanual page as shown in FIG. 20 which shows the contents of theelectronic manual files retrieved in step S308. The control unit 10controls the CCU 11 to transmit the web page data to the terminal 500(step S309).

As shown in FIG. 20, the electronic manual page also includes a buttonlinking to pages for presenting differential manuals between the targetmodel and the user's current model. The button (hyperlink) invisiblyincludes URL information specifying the pages of the differentialmanual. In response to selecting the button, the terminal 500 transmitsthe URL information is sent to the center 100.

When the CCU 11 of the center 100 receives the URL information from theterminal 500 (step S310: YES), the control unit 10 selects theelectronic manual files representing the functions of the target modelbeing different from those of the user's current model (step S311).

The control unit 10 executes the CGI program and the like in the programmemory unit 13 to generate web page data representing an electronicmanual page showing an example of the contents of the electronic manualfiles selected in step S311 The control unit 10 controls the CCU 11 totransmit the web page data to the terminal 500 (step S312), andterminates the operation.

According to the above operation, the center 100 provides the user withthe differential manuals between the current model and another modelwhich is a target for comparison. Therefore, the user can effectivelystudy about nominees for upgrading.

According to this embodiment as described above, when the registeredcustomer requests the electronic manual to the center 100, the center100 automatically selects the electronic manual files and provideshim/her with them without asking the user to input any information forspecifying the model. Thus, the customer can quickly obtain a desiredelectronic manual.

Further, if the user wants to study products (models) other than onehe/she currently uses before buying, the user can requests the center100 to provide him/her with differential manual describing functionaldifferences between the target model and the current model with justdesignating the target model (model name, model No., or the like).Accordingly, the user can study about target models efficiently. Sinceinformation regarding to the differences is transferred, it reducesconnection time for browsing the manuals.

In a case where a customer upgraded the copier 300 and it has beenwithin a predetermined period (for example, 1 month), the center 100provides the customer with option for the differential manual betweenthe current model and the former model.

According to this structure, the user can learn about significantfeatures of the upgraded model quickly. Since only necessary andsufficient information is transferred, it reduces connection time forbrowsing the manuals.

Since even anyone other than the registered customers can browse theelectronic manuals for a desired model, a person who plans to buy aproduct can study about target models in view of usability beforebuying.

In the above embodiment, the electronic manual pages are prepared on theweb site of the manufacturer/vendor of the copier 300. However, theelectronic manual providing page may exist solely on the Internet 3. Inthis case, the customer identification may be done at the time acustomer accesses the electronic manual providing site.

The center 100 of the above embodiment may be realized not only by adedicated system, but also by a general computer system. For example, itis able to establish an information providing site which executes theabove describe operations by installing a program for executing theabove-described operations into a general-purpose computer from a mediumwhich stores the program (such as a flexible disk, CD-ROM, or the like).

In this case, it may employ arbitrary means for providing the program tothe computer. For example, the program may be distributed throughcommunications networks, a communications system, or the like. In thiscase, the program may be uploaded on a bulletin board system (BBS) on acommunications network, and the program may be superimposed on a carrierwave signal, so as to be distributed through the network. And, the abovedescribed operations can be done by running thus distributed program inthe same manner for the other application programs under the control ofthe OS (Operating System).

According to the present invention, an electronic manual for a productbeing used by a customer is automatically selected and provided, and anelectronic manual describing functional differences between targetproducts is provided to users.
